Depiction of a red blood cell in an isotonic solution. A solution is isotonic when its effective osmole concentration is the same as that of another solution. In biology, the solutions on either side of a cell membrane are isotonic if the concentration of solutes outside the cell is equal to the concentration of solutes inside the cell.
The main intravascular fluid in mammals is blood, a complex mixture with elements of a suspension (blood cells), colloid , and solutes (glucose and ions). The blood represents both the intracellular compartment (the fluid inside the blood cells) and the extracellular compartment (the blood plasma). The average volume of plasma in the average ...
It occurs in a hypotonic environment, where water moves into the cell by osmosis and causes its volume to increase to the point where the volume exceeds the membrane's capacity and the cell bursts. The presence of a cell wall prevents the membrane from bursting, so cytolysis only occurs in animal and protozoa cells

Thus, a biologically isotonic solution (e.g. "isotonic saline") is hyposmotic (osmolality = 287 mosmol/kg H20) with respect to blood plasma (301 mosmol/kg H20) or the interior of red blood cells, because both these solutions (blood plasma and red cell cytoplasm) contain urea, glucose and bicarbonate which pass freely through the cell membrane.

In hypertonic solutions water flows out of the cell and the cell shrinks (plasmolysis). In hypotonic solutions, water flows into the cell and the cell swells ( turgescence ). Osmotic shock or osmotic stress is physiologic dysfunction caused by a sudden change in the solute concentration around a cell , which causes a rapid change in the ...
